These things spawn on The Island at the bottom right of the map near the Lava Cave. These cheeky little buggers are more than happy to ruin your day by swarming and stunlocking you and your tames nonstop unless you are on a Basilosaurus, which is the only creature that is immune to their attacks. If you don't have a Basilosaurus, lure them close to shore and cheese it with a spear or pike, better yet pray that they beach themselves and die.

Is there a mod that removes these and eels from the game?

These guys killed SO many of my Dinos in my early game, when I got god console i mudered every one of them (I’m on mobile)

Tip: dont go near the cool looking mini-beacons.

These mfs trigger a deep hatred in my soul. I don’t even kill them for bio toxin anymore, I just wanna hear that jellyfish death sound and watch them flip over as their life ends.

I will never forgive these evil buggers I decided to roam the water on my Barry and was like “lol squishy ass jelly’s what will they do?” Dismounted killed danced on and my bob (baryonyx) died a minute later. I hate these things

Step one-get overpowerd sword

Step two- get overpowerd armor

Step three- atack a pack and u will still die

I hate Them!!!!! I love killing them!!!!! There dumb Idiots!!!!!!

When battling these creatures make sure not to get tames involved, just bring a sword and a in 1-2 slices they will die

If you want to kill one all you have to do is find one close to shore and Jab it with a spear it will aggro and chase you run to the sore turn around and stab him to death. DO IT FOR MY DILO JUNGLE

RIP JUNGLE

KILL ALL JELLIES

M pteranodon killed another pteranodon then my moschops went to havrvest it’s corpse and these stupid jellyfish come out of nowhere and kill him up if you hate them R.I.P moschops

Kill it by letting it follow you to the shore then kill it because it killed my para-something that looks like an elephant

Pro tip. STAY OUT OF THE WATER WHEN YOUR NOT ON A BASSI OR ANY SHOCK IMMUNE WATER TAMES. This thing will kill you your tames your family your friends and all your progress

To farm these things to get the best keep-unconscious resource in the game, Bio-toxins, you will need a basilosaurus because they don’t get affected by jellyfish at all. You don’t need to ride it just target it to fight these things. After that stuff the toxin in a ceramic vase because you can preserve it in there forever as long as it doesn’t break.

Up this tip if you hate this stupid jellyfish. It killed my Icthy and my Raptor. 1 up = 1 rip 4 my raptor and icthy.

I HATE THESE THINGS but there quite dumb it’s easy to kill these things all you have to do is attract them to the Beach get a bow and arrow get on to land and start to kill them

If you are annoyed by cnidira(jellyfishes) tame a basilosoraus or tusso , basilo is easier just kill the mantas surrounding it (using sarco or baryonx , meg) and feed it exceptional kibble or prime meat (raw meat is fine as well) the use the basilo to fight the jellyfishshes since they can't be stunned or shocked , killing jellyfishshes becomes easier with the basilo

my level 53 (Nilah) and level 61 (Spiny) spinos were actually able to take these guys out with no problem. they saved my mesopithicus (Maverick).

Basi will bust their ass and you don’t get knocked off

Was riding my trusty Baryonix, my bro came everywhere with me. Cleared lands, cleared caves, destroyed dinos far bigger and better than it. The best.

Then I had a lack of judgement.

Went to get some black pearls. Basically wiped out the ocean of other creatures, destroyed about 5 alpha sharks and hopped off to gather. Turned around to see a single jellyfish that I swear wasn't there before approach the baryonx. I checked about 6 times before dismounting, I knew it wasn't there. I tried to save him though I knew it was too late.

My survivor woke up in bed as I just watched the screen knowing that despite being set to flee combat, it was only a matter of time until I got a notification on screen telling me that my main man had been drained of 6k health in a single stunlock and passed away.

These mother f's are the most ridiculous, over powered and pure awful creature not just in Ark, but in any game. How have they not been nerfed so that you don't lose basically any dino other than the Basi to even one jellyfish with a stunlock of death?
